The information given on a Type 3.1/3.2 Inspection Certificate are actual test results from the material in the lot from which the steel products have been supplied (formally referred to as "specific testing"). A 3.1 Inspection Certificate is endorsed only by the manufacturers own representative who has to be independent from the manufacturing process (Test House Manager) whilsta 3.2
Inspection Certificate has additionally been countersigned by an independent inspectionauthority who has confirmed that the testing and inspection process demanded by the specification have been adhered to correctly.

FranThe main difference between 3.1 and 3.2 certification in materials is the level of control and inspection conducted. A 3.1 certification includes both the material test report and inspection certificate, whereas a 3.2 certification includes additional verification by an independent third party. This extra level of scrutiny provides higher assurance of the material's quality and compliance with standards.

What is EN 31 MATERIAL?
EN 31 is a high carbon alloy steel with additions of chromium, molybdenum, and vanadium. It is commonly used in the manufacture of bearings, cutting tools, and surgical instruments due to its high wear resistance and toughness properties. The material is known for its good hardenability and ability to retain its strength at high temperatures.
What is the difference between phosphorus 31p and 32p?
Phosphorus-31 (31P) is a stable isotope of phosphorus that is commonly used in nuclear magnetic resonance (NMR) spectroscopy, while phosphorus-32 (32P) is a radioactive isotope of phosphorus commonly used in biological research for labeling and tracking DNA and proteins. The main difference is the stability of the isotopes, with 31P being stable and 32P being radioactive.
What is nuclear symbol for Phosphorus 31?
The nuclear symbol for Phosphorus-31 is ^31P.
If the mass of an electron is 9.10939 x 10-31 then show 1 2 3 and 4 of its significant figures?
Significant figures are very important when it comes to calculations. If the mass of an electron is 9.10939 x 10-31 then its significant figures are: 9 x 10^-31( correct 1 significant figure), 9.1 x 10^-31 kg ( correct to 2 significant figures), 9.11 x 10^-31 (correct to 3 significant figures), and 9.109 x 10^-31 (correct to 4 significant figures).
